AI SQL assistant that writes, fixes and runs queries on your real schema
Describe the result you want in plain English or another language and get SQL written with your real table and column names in the dialect of your chosen database.
Paste any query — generated or hand-written — to get a clause-by-clause explanation, corrections with reasoning, performance rewrites and clean formatting.
Execute queries against a connected read-only connection and inspect the returned rows and timing directly in the interface.
Expose your database to Claude, ChatGPT in developer mode, Cursor or your own agent through a governed MCP endpoint and a REST API with per-agent keys.
Real-time AI answer engine and research workspace combining live web citations with frontier reasoning models.
Executes multi-step iterative web and document research across hundreds of sources, cross-checking facts and generating structured, citation-backed analytical reports that can be exported as PDFs or shared as interactive Perplexity Pages.
Lets Pro and Max subscribers switch dynamically between Perplexity's in-house Sonar models and top external models (including Claude 4, o3-pro, and Gemini) or compare multi-model reasoning outputs side by side.
Provides dedicated project workspaces where users upload local PDFs, spreadsheets, and text files, configure custom assistant instructions, and run queries that combine private document retrieval with live internet search.
Extends Perplexity from passive Q&A into agentic execution, turning high-level user requests into completed workflows, multi-tab browser actions, and automated data synthesis via the Comet ecosystem.
